Try Client Credentials Grant¶
The Client Credentials Grant is one of the four grant types in the OAuth 2.0 specification. For more information about this grant type, see Client Credentials Grant.
Running the application
Before you begin
You must first
set up the
playground sample webapp.
in order to try the following scenario.
- Visit the URL http://wso2is.local:8080/playground2/oauth2.jsp to start the application.
Enter the following details and click Authorize.
Authorization Grant Type: Client Credentials
Client ID: (the client id received at the application registration)
Client Secret: (client secret received at the application registration)
Access Token Endpoint: https://localhost:9443/oauth2/token
The playground application will send a token request to the token endpoint of the WSO2 Identity Server using the following format.
POST https://<host>:<port>/oauth2/token Authorization: Basic [Base64encode(Client-ID>:<ClientSecret>)] Content-Type: application/x-www-form-urlencoded grant_type=client_credentials
POST https://localhost:9443/oauth2/token Authorization: Basic Q3g0TEtGTk9iZXVYb2N4N3hnT3B6NXZmekZvYTogVWRUNm5XbnFXWkdnNDFHWnI5TXBTWGs5eU04YQ== Content-Type: application/x-www-form-urlencoded grant_type=client_credentials
At this point the application receives the Access Token. Enter the introspection endpoint (i.e, https://localhost:9443/oauth2/introspect ) and click Get TokenInfo to get the token information.

OAuth 2.0 Token Introspection defines a protocol that allows authorized protected resources to query the authorization server to determine the set of metadata for a given token that was presented to them by an OAuth Client. This metadata includes whether or not the token is currently active (or if it has expired or otherwise been revoked), what rights of access the token carries (usually conveyed through OAuth 2.0 scopes), and the authorization context in which the token was granted (including who authorized the token and which client it was issued to). Token introspection allows a protected resource to query this information regardless of whether or not it is carried in the token itself, allowing this method to be used along with or independently of structured token values.
Now you should be able to see the access token information as seen below, as long as the provided access token is valid.
